APPARATUS FGR PRODUCING THREAD MOUNTINGS..

Application filed March 31, 1924:.

My invention relates to thread grouping and mounting and has for its object to provide a machine for producing thread mountings to be cut up into strips for display cards, to expedite and cheapen the cost of thread grouping and mounting; to provide a machine which can be used to mount groups of a width substantially uniform, several groups being made up of threads of different thickness. A further object of the invention is to produce amachine which acts to mount groups of threads upon an extended web supplied from a roll and received by a take-up. It further has for its object to bring about other improvements and produce other novel and valuable results as will appear from the description as follows:

The following is a description of an em bodiment of my invention, reference being had to the accompanying drawings, in which,

of the dauber roll.

Referring more particularly to the drawings, .2 is the main frame of the machine which carries aguide roller 4 over which a web 6 of paper such as cardboard passes from a supply drum 8 to a tension device 10, this tension device being an adjustable spring clamp as shown in Figs. 2, 3 and 4, through which the web is drawn. The web 6 then passes between two rolls 12 and 14 shown in detail in Fig. 6, which rolls I term registering rolls because they are punch and die rolls for forming perforations in the edges of the web. The roll 12 isprovided with punches 16 near each of its ends andthe roll 14 is provided with corresponding dies 18. The web contacts with the lower roll only, the two rolls being spaced apart and the upper roll serving merely as a carrier for the punches. The punches and dies are spaced apart by that the perforations in the paper are equally distant from each other.

From the registering rolls the web passes around a drum 20 which I call a registered drum, the same being provided with property spaced pins 22 (see Fig. 5) which enter correspondingly spaced holes 24 previously formed in the edges of the web (see Fig. 3).

From the registered drum 20 the web passes to. a take-up mechanism which comprises a drum 26. This drum is removably mounted upon a shaft 28, which shaft is driven through a. friction device by a sprocket chain 30.

This friction device shown in Fig. 10 consists of a flanged member 32 which is secured to the shaft by a set-screw, a second flange 34 and an intermediate member 36 carrying the teeth for the sprocket chain and held between the plates 32 and 34: under yielding pressure due to the spring 38, the plate 34 being keyed to the hub of the plate 32 so as to be movable endwise.

The take-up drum 26 is removably secured to the shaft 28 by a stud 40 which is mounted upon a flange 42, the head of. the stud passing through the web 44 of the drum, a slot 46 with an enlarged opening at one end being provided for that purpose.

In the operation of the machine, groups of thread are supplied to and mounted upon the web 6 during its passage from the supply roll 8 to the take-up 26. or this purpose an angular creel as is provided adapted to carry a plurality of series of bobbins on each side. This creel is triangular in shape and provided with vertical bars whose outer faces are parallel to the central axis of the triangle. This results in having the bobbins 52 properly stepped so that the thread from each bobbin will be kept sep arate, as shown in Fig.3.

At the front at the creel there are brackets or plates at, each having on both sides otits center a series of holes 56, the holes corresponding to the number oi bobbins in a horizontal row of the creel as shown in Fig. 3.

hese holes are spaced apart by the same amount as the bobbins in each horizontal row are axially displaced. In addition, the thread from any one bobbin. with the exceptiion of those in the first vertical rows, passes through a guide 58 mounted on the vertical bar next ahead of the bar carrying said bobbin as shown in Fig. 2. The guide for any bobbin is in a plane parallel to the medial plane of the creel and intersecting the core of the bobbin at its center. In addition to these guides, some of the vertical bars 50 have supporting arms 60 which assist in guiding the threads passing to the brackets 54. These arms are long enough to extend beneath the threads from all bobbins located tothe rear thereof in any one row and preterably have upturned ends.

The brackets thus each deliver two groups of threads. one from each side. When the bobbins are properly selected and arranged, the threads in any one group are of the same size and character and by the means hereinafter described are kept together and arranged in parallel order until they are applied to and securely mounted upon the web 6.

Thus the left-hand group of threads delivered from the upper bracket 54, as shown in Fig. l, is passed successively through the selecting spacing and tension plates 62-45%, each thread passing through separate perforations 66 and 68 shown in Fig. 8 of said plates. the threads being so passed as to not cross one another in going from the bracket fill-to the plate 62. These perforations are arranged in inclined rows, substantially parallel to one another. litter passing through the plate (i l the threads pass beneath a ten sion rod TO and over a tension rod and thence over a spacing bar 7 which spacing b'Jar is provided with a plurality of grooves. ohc groove for each group otthreads. The inclination of the rows holes 68 results in .layhio; the threads side by side as they pass beneath the rod 'r't as shown in Fig. 8. The group then passes oi'e'r a tension rod 76 and beneath a spacing bar F8, whicii brings it in close proximity to the drum 20 carrying the paper web on which it is to be mounted.

The threads inpassing through the holes in plate 6 to and beyond the spacing bar 78 have their parallelism maintained so that when they are laid upon the web they are parallel to one another and also parallel to the axis of said web, or, in other words, to the plane which is at right angles to the axis oi" the registered roll 20 which carries the web.

The spacing bars 74 and 7 8 have one side cut away. On account of this construction the spacing of the threads can be varied somewhat by adjusting these bars angularly. The thread is drawn across the corner i' ormed by the cut away side as shown in Fig. 12. In the bar T l the spacing notches are semi-circular. In the bar 78, however, I prefer to make them with slanting bottoms as shownsomewhat exaggerated in Fig. 11, which slant is slightly decreased as the threads decrease in' size. This automatically lays them closely side by side with the desired compactness in the groups. An average slant of about one thirty-second of an inch in quarter inch grooves gives satisfactory results.

Before the threads are brought into contact with the web in the manner described. the web is provided with transverse lines of glue 80. shown in Fig. 8, there being two transverse lines of glue placed quite closely together and preferably two additional lines of glue as shown, the four lines constituting a composite band of glue. These transverse'lines of glue are applied by a rotary dauber 82 having four daubing arms, each of which is provided with four ridges 83. as shown on an enlarged scale in Fig. 18. This dauber receives its glue from an intermediate roll 84, which in turn receives its glue from a feed roll 86 which dips into glue within a tank 88 and is engaged by a scraper 87 The rolls 8l and 86 and scraper 87 are carried by an adjustable support. The space between the second and third ridges 83 of the dauber is preferably greater than be tween other acent ridges so as to provide ample cutting space.

The rolls 8d and 86 shown in Fig. 4 are geared together as shown in Fig. 2. and are driven by an intermediate gear 90 which meshes with a gear 92 carried by the shaft 94 ot the registered drum and rotating therewith directly drives the gear 93'. The daub er roller sea 95 meshes directly with and is driven by the gear 92. The shaft 94.- also carries a sprocket wheel 96, which through the sprocket chains 30, drives the take-up drum 28. The gearing is such that the peripheral speeds of the drum 20, the rolls ea and 86, and the dauber 89. are equal. 'The take-up drum tends to move at a slightly faster rate which causes the friction drive to slip and mainta'ns a tension on the web.

The gear 92 also drives a pressure roll 98 shaft of the registered through the gear 100, which roll is carried by an adjustable yoke 101 and acts to press the threads upon the web 6 after they have been applied to the glued surface thereof.

The dauber device is carried by an adjustable hanger which swings about the shaft 102. When this hanger is withdrawn, the dauber can be removed forcleansing. Such cleansing is necessary if the machine is allowed to remain idle for any considerable length of time. hen the dauber is removed, the gear 90 can be shifted out of mesh with gear 93 and the hand wheel 97 actuated to cause the rolls 84 and 86 to revolve. These rolls under those conditions can be easily washed by removing the glue tank 88 and supplying water to the surrounding receptacle 104. This receptacle is mounted upon levers connected by the links 106-107 so that it can be raised and lowered as desired, the detent 108 engaging a notch in quadrant 109 being provided for holding it in elevated position. The link 107 is adjustable in length and is adjusted so as to bring the four points of support for the re ceptacle into the same plane.

The mechanism as a whole is driven by power supplied to the fast pulley 110 mounted upon the worm shaft 111, the worm of which engages a worm wheel 112 on the shaft 94 as shown in Fig. 2.

The rolls 12 and 14 shown in Fig. 6 being geared together and having punches and dies which must work in synchronism, means is provided for adjusting one relatively to the ot e1 Thus the shaft of theroll 12 is provided with a flange 114 to which the gear 116 is held by screws 118. The gear 116 is provided with slots so as to permit it to beadju=ted relatively to the flange 114. It is driven by the gear 92 through an intermediate gear 117, as shown in Fig. 2.

Somewhat similar means are adjusting the registered tion to the rolls 12 and 22 upon the registered proper relation to the the rolls 12 and 14.

provided for drum 20 with rela- 14 so that the pins drum may be in punches and dies of To accomplish this the drum 20 is provided with a flange 122 having lots 124 through which adjusting screws 126pass.

The left-hand portion of Fig. 3 shows a plan view of the end of the web after it has traversed the machine before described, the same consisting of the base portion 6 having the groups of threads 200 secured thereon by transverse strips of adhesive 80, the groups being of substantially the same width and the number of threads in any one group varying with their size.

To summarize the method carried out by the machine, a web of paper such as cardboard is supplied from a roll 8 and passes over the guide 4 through the tension device slow and the take-up 120 for the screws 118 a and between istere d drum 20 and thence to the take-up, which take-up, on account of its friction drive, keeps the web under tension. As the we is passing around the registered drum 20 it is supplied with transverse lines of glue y the dauber of the gluing mechanism and after being so supplied it is also supplied with substantially uniform parallel roups of parallel threads which are laid upon the web parallel to its axis. These threads are thus brought in contact with the strips of glue. They are then forced into more intimate contact therewith by the presser roll 98 so that the take-up winds up a long strip composed of parallel groups of parallel threads mounted u on a paper backing. he movement of the parts is comparatively is situated quite a dis tance from the other parts of the machine so that the glue dries sutliciently before it is wound upon the take-up. In utilizing my product I subsequently remove the take-up drum with the web Wound thereon and cut the Web into transverse sections by meansof a cutting machine which isthesubject of another application filed me on March 31, 1924, Serial No. 703,046 forming strips which are mounted with screens to form display cards.

.As stated, the widths of the groups of threads depend upon the size of the threads and the number of threads employed. Preferably all the groups are tially the same width and my process I therefore, Where the threads use less threads in a group which is not possible by the old methods heretofore employed creases as the size of the threads increases.
